About Griseargiolestes eboracus (Tillyard, 1913)
Griseargiolestes eboracus (Tillyard, 1913) is a species of Australian damselfly belonging to the family Argiolestidae. It is commonly known by the common name grey-chested flatwing. This species is endemic to eastern Australia, and it inhabits bogs there. Griseargiolestes eboracus is a medium-sized damselfly, with a black-green metallic body that has yellow markings. Adult individuals have pruinescence on their body, but not on their tail. Like all other members of the family Argiolestidae, this damselfly rests with its wings held outspread. Griseargiolestes eboracus looks similar to Griseargiolestes griseus, a species that occurs south of the Hunter River in New South Wales.
